Telescoping bed platform

ABSTRACT

Disclosed is a bed platform and system for use in an enclosed or partly enclosed space, such as, a cargo space of a vehicle, such as, a van, camper, or truck, among others. By one approach, the bed platform consists of interleaved portions of panel portions that permit relative lateral motion of the panels. In some configurations, the panel portions are adjustable such that the bed platform can be fit into differently sized vehicle cargo spaces. In addition, the systems described herein also may permit the bed platform to be adjusted or moved to different heights even though the wall configurations may be different along the height thereof.

CROSS-REFERENCE TO RELATED APPLICATION(S)

The present application is continuation of U.S. patent application Ser. No. 16/410,869 filed on May 13, 2019, which claims the benefit of U.S. Provisional Application No. 62/670,586 filed May 11, 2018, both of which are incorporated herein by reference in their entireties.

TECHNICAL FIELD

The invention generally relates to a utility platform for use in a passenger vehicle such as a van, camper, or truck or other enclosed or partly enclosed spaces.

BACKGROUND

Prior bed platforms for use in vehicles, such as vans, typically, are specifically designed to fit a particular dimension of the vehicle and are generally set at a specific height or location once installed. For example, to install a conventional bed platform into a vehicle, L-brackets are mounted to the walls of the vehicle and the bed is then mounted to the L-brackets. Such bed platforms typically have a fixed length and are generally not adjustable.

Further, in light of their fixed length, even if they are height adjustable, the shape of the cargo space may cause problems for such adjustment. More particularly, because the cargo walls of a conventional vehicle are typically not straight along their height, moving a conventional bed platform up or down along the vertical dimension (height) of a vehicle generally causes the bed platform to be too long or too short (or too wide or too narrow) to fit the width of the vehicle. If the platform is too long to fit the width of the vehicle, then the bed platform may not be stably supported in a level or generally horizontal orientation. If the bed platform is too short, then the bed platform will not be able to be mounted to the walls of the vehicle or there will be a margin between the edge of the bed and the interior wall of the vehicle. In this manner, the margin around the platform may permit unwanted lateral motion of the platform bed, which may make the installation unstable, even though it is mounted to the interior walls of the cargo space of the vehicle. This margin also may be a space into which items or persons may accidentally fall. The process of installing a conventional bed platform is also generally time consuming given the precision required to avoid having a platform that does not fit or has a significant margin that permits relative movement.

DETAILED DESCRIPTION

A telescoping bed platform for use in an enclosed or partly enclosed space, such as in a vehicle, is described herein. The platform has panels that telescope to permit installation of the bed platform into spaces of various sizes. More particularly, permitting portions of the panels to move relative to one another gives the overall platform a variable width, thereby permitting the platform to be installed into cargo spaces with a number of different widths. The ability of the individual panels to telescope also permits easy adjustment of the height at which the platform is installed. In this manner, the telescoping bed platform is usable in a number of different vehicles having differently configured cargo spaces.

By one approach, the variable bed platform has multiple panels that move relative to one another to expand or retract the size of the platform. To install, the bed platform the panels include coupling mechanisms for securing the individual panels forming the bed platform to the interior wall of the cargo space of the vehicle. Such coupling mechanisms include, for example, bed rails having a specific geometry installed along the cargo walls and corresponding geometry at the ends of the panels to permit the panels to be secured into the cargo space by attaching to the bed rails. Further, in some embodiments, a telescoping bed platform system also includes tracks installed along the walls of the cargo space, where the tracks can have the bed rails mounted thereto, such that the bed rails can be moved up and down along the tracks allowing repositioning of the bed platform to different heights within the cargo space.

In one illustrative embodiment, a modular bed platform 80 includes multiple panels 100. With regard to FIG. 1, a modular bed platform 80 having three individual bed platform panels 100 a, 100 b, and 100 c is illustrated. The modular bed platform 80 is shown installed in a vehicle 50 having a first interior side wall 10 and a second interior side wall 15 opposite thereof. The vehicle 50 may be, for example, a Mercedes Sprinter van, a Ford Transit van, or any other vehicle with sufficient cargo space (i.e., sufficient horizontal and vertical dimensions) to accommodate a bed platform as described herein. The bed platform panels 100 a, 100 b, and 100 c can extend and retract to increase and decrease their length (and thereby adjust the width of the modular bed platform 80) in order to properly fit varying widths of a vehicle such as vehicle 50.

By one approach, an individual panel 100 includes a panel surface 120 that is comprised of a first panel surface 144 and a second panel surface 160 with interleaved projections 126. The individual panels 100 each include a frame 122 having at least a first frame section 130 and a second frame section 132. In one embodiment, the first and second panel surfaces 144, 160 have coupling mechanisms associated therewith to secure the first and second panel surfaces to the interior walls of the cargo space of the vehicle 50. Further, the first and second panels surfaces 144, 160 are generally movable relative to one another to increase or decrease the length of the panel 100 and the overall width of the bed platform 80 comprised of the panels. To that end, the individual panels 100, in one illustrative embodiment, have a frame 122, which may be comprised of multiple pieces, such as a first frame section 130 associated with the first panel surface 144 and a second frame section 132 associated with the second panel surface 160. In one illustrative approach, the frame 122 associated with the panel 100 has multiple sections that telescope together.

In another configuration, an individual panel 100 also includes coupling element(s) or hardware that connects the individual panel 100 to the interior wall of the cargo space, as described further below. Depending on the configuration of the hardware, the coupling elements may be incorporated into the frame or may be an additional discrete structure. In addition, depending on the type of material comprising the panel surface 120, the hardware also may provide support or structural rigidity to the panel surface 120. For example, the frame 122 may also be used, in part, to facilitate coupling of the individual panels 100 to an interior wall of the cargo space and to reinforce the panel surface 120.

The bed platform panels 100 a, 100 b, and 100 c described herein can be scaled to a variety of dimensions to accommodate the various uses that will become apparent to one of ordinary skill in the art based on this disclosure. In some configurations, the bed platform panels 100 a, 100 b, and 100 c have an adjustable length to accommodate users of various sizes or to fit various installation spaces. For example, the bed platform panel 100 c is illustrated as having a both a wider and a narrower portion along its length, with the wider portion being designed to abut the rear door of the vehicle 50 thus creating a continuous bed platform that substantial abuts the walls 10, 15 of the vehicle as the rear wall 20 of the vehicle 50, as illustrated in FIG. 2. FIG. 2 illustrates a top view of an embodiment of a portion of the vehicle 50. As can be seen, the bed platform panels 100 a, 100 b, and 100 c together form a nearly continuous surface within a portion of the cargo space of the vehicle 50, such that the modular bed platform 80 abuts the first and second side walls 10, 15 of the vehicle 50 and the rear wall 20 of the vehicle 50. The rear wall 20 of the vehicle may be formed in part, of, for example, one or more doors.

FIG. 17 illustrates the panels 100 a, 100 b, and 100 c in a stowed configuration against a wall 10, 15 of a cargo space. The panels are supported from the bottom by brackets 1705, 1710. The panels 100 a, 100 b, and 100 c are held tight to the wall 10, 15 by straps 1605, 1610, and 1615.

Because individual panels 100 a, 100 b, 100 c have an adjustable length as described in detail below, the individual ones of the panels 100 a, 100 b, 100 c can be used in a bunk or a bed configuration using the straps 1605, 1610, 1615 and the brackets 1705, 1710. For example, as illustrated in FIG. 16 an individual one of the panels 100 a, 100 b, 100 c may be oriented across the width of a cargo space to form a bench. In such a configuration, the individual one of the panels 100 a, 100 b, 100 c may be coupled to a bed rail such as bed rail 125 a and 125 b via the straps 1605, 1610, 1615 with one corner of the bed resting on the a bracket such as bracket 1705.

In another configuration, an individual one of the panels 100 a, 100 b, 100 c may be oriented along the length of a cargo space to form a bunk as illustrated in FIG. 18. In such a configuration, the individual one of the panels 100 a, 100 b, 100 c may be set across the brackets 1705, 1710 and supported on the opposite side of the side that is support by the brackets 1705, 1710 by straps such as the straps 1605, 1610. In both the bed and the bunk configuration straps may couple directly to the individual one of the panels 100 a, 100 b, 100 c or be coupled to the individual one of the panels 100 a, 100 b, 100 c through intermediary hardware. Likewise the straps may couple, at the end not coupled to the individual one of the panels 100 a, 100 b, 100 c, directly or through intermediate hardware to the ceiling or walls of a cargo space, a track, such as vertical track 150 b, or a bed rail, such as bed rail 125 a or 125 b.

In one illustrative configuration, the bed platform panels 100 a, 100 b, and 100 c are coupled to the walls 10, 15 of the vehicle 50 via bed rails 125 a and 125 b. The bed rails 125 a and 125 b are in turn coupled to the walls 10, 15 of the vehicle 50 via tracks 150 a, 150 b, 150 c, and 150 d, such as horizontal or vertical tracks. In operation, the tracks 150 a, 150 b, 150 c, 150 d have a generally vertical orientation so that the tracks may be used to permit the height of the modular bed platform 80, or any individual panel 100, to be easily and quickly adjusted. By one approach, the vertical tracks 150 a, 150 b, 150 c, 150 d are secured directly to the walls 10, 15 of the vehicle 50, such as by, for example, screws, rivets, nails or similar securement mechanisms.

FIGS. 3 and 4 illustrate two different bed platform panels, 100 a and 100 c respectively. The panel 100 a, shown in FIG. 3, is generally more narrow than the panel 100 c, shown in FIG. 4. These, and other panels, may be combined together to form a modular bed platform 80. The bed platform panel 100 a also corresponds to panel 100 b. In addition to the width, the only other functional difference between the bed platform panels 100 a and the bed platform panel 100 c is the difference in the shape. In one illustrative approach, the panel portion 107, shown in FIG. 3, has a more consistent width along the length of the body (i.e., until the projections 129), as opposed to the shape of panel portion 109. As described above, with reference to FIG. 1 and FIG. 2 the shape of the panel portion 109 of the bed platform panel 100 c has been modified so that it substantial abuts the rear wall 20 of the vehicle 50. Similarly, illustrated features between the panels 100 a, 100 b and the panel 100 c are shared amongst each of the panels 100 a, 100 b, and 100 c, and unless a structure is specifically distinguished the structures and functions of the panels 100 a, 100 b, and, 100 c should be interpreted as being substantially identical. This detailed description will proceed by describing the structures and functions of the panel 100 a, but it should be understood that the panels 100 b and 100 c also have similar structures and functions.

In one configuration, the bed platform panel 100 a, shown in FIGS. 3 and 5 has two panel portions 105, 107 that are movable relative to one another. By one approach, the panel portions 105 and 107 have portions that telescope relative to one another. FIG. 3 illustrates the panel portions 105, 107 in a fully nested, contracted, or retracted position relative to one another, and FIG. 5 illustrates the panel portions 105, 107 in a fully extended position relative to one another. In one illustrative embodiment, the panel portions 105, 107 each have a handle portion or opening 168, 166 that allow a user to easily grasp and manipulate the bed platform panels 100 a. As illustrated, the panel portions 105, 107 also have a number of tines, slats, or projections 128, 129 that are arranged alternately with one another as illustrated, for example, in FIG. 3. The panel portions 105 and 107 may have more or less tines, slats, or projections than illustrated in for, example, FIG. 3. When the panel portions 105, 107 of the bed platform panels 100 a are separated by lateral motion from one another, free space or an opening 110 is created between the tines, slats, or projections 129. The alternating projections 128, 129 permits the modular platform bed 80 formed of the panels 100 to be expanded or retracted to properly fit within a cargo space, while still providing firm support for a mattress, one or more individuals, and/or for support of baggage or cargo, among other items.

FIG. 6 illustrates the underside of the bed platform panel 100 a. FIG. 6 illustrates the bed platform panel 100 a in a fully extended position with the panel portions 105, 107 partially pulled apart from one another. As shown on the underside thereof, the panel portion 107 has a the first frame section 130 associated therewith. The first frame section 130 includes outer parallel frame members 134, 136 running parallel to each other parallel to the edges of the panel portion 107. By one approach, the frame portions 134, 136 are adjacent the outer edge of the first panel surface 144, whereas in other configurations, the frame portions 134, 136 may be disposed a distance from the edge of the first panel surface 144. The frame members 134, 136 are connected to each other and fixed relative to one another, at least in part, by cross members 138, 140 and end member 142 as illustrated in FIG. 6. In one illustrative embodiment, the panel portion 107 has a first panel surface 144 that may include a rigid, upper surface portion. The rigid first panel surface 144 may be, for example, a laminate, metal, composite material, or a wood such as bamboo, among other materials. The projections 128, 129 may be formed out of the rigid surface portion as illustrated in FIG. 3. The first panel surface 144 may be secured to the frame portions 134, 136 of the frame 130 by means of, for example, nuts and bolts, screws, rivets, welding, or an adhesive.

In some embodiments, the first frame section 130 also has a latch receiver plates 146, 148 mounted to outer parallel frame members 134, 136 respectively. By one approach, the latch receiver plates 146, 148 receive a latch mounted to the cross member 152 of the panel portion 105 and together with the latch the latch receiver plates 146, 148 prevent the bed platform panels 100 a and the portions thereof 105, 107 from moving relative to one another, i.e., extending or retracting. The latch receiver plates 146, 148 have a number of intermediate locking position along their length illustrated by square openings and the final locking position illustrated as a deep indent. When the bed platform panels 100 a are fully retracted, the latch can be inserted into the deep indent to keep the bed platform panels 100 a in a fully retracted position.

The panel portion 105, as shown in FIG. 6, also has an inner parallel frame portions 154, 156 disposed along opposing, lateral edges of the panel portion 105, as illustrated. The outer parallel frame members 134, 136, in one configuration, are generally sized to receive at least a portion of the inner parallel frame members 154, 156. By one approach, the outer parallel frame portions 134, 136 have a generally rectangular cross section with a pair of inward facing walls on each of the respective frame portions 134, 136. In use, the inner parallel frame portions 154, 156 may telescope into and out of the outer parallel frame members 134, 136 in the lateral direction. The inner parallel frame portions 154, 156 are connected, at least in part, to each other via an end member 142. The end member 142 is connected to the cross member 152 via a rigid surface structure 160. The rigid surface structure 160 may be connected to the cross member 152 by means of, for example, nuts and bolts, screws, rivets, welding, or an adhesive. The rigid surface potion 160 may be, for example, a laminate, metal, composite material, or a wood such as bamboo, among other materials. The projections 128 may be formed out of the rigid surface portion as illustrated in FIG. 3.

In one illustrative approach, the projections 128 of the panel portion 105 each are each secured to the cross member 152 such that the cross member 152 sits between the projections 129 and latch receiver plates 146, 148 as illustrated in FIG. 7 (view of the bottom of the panel, the bottom facing the ground). In an alternative embodiment, the inward facing walls of the frame members 134, 136 may be cut away in the portion running approximately the length of the latch receiver plates 146, 148. By one approach, the cross member 152 connects to the inner parallel frame members 154, 156 through the cut away portion of the frame members 134, 136. In one embodiment, the panel portion 107 also includes a piston arm 605 and tensioning device 610 so that the panel portions 105, 107 are biased to a fully extended position, such as shown partly in FIG. 5. In some embodiments, the cross member 152 further include a tab 164 (FIG. 6) that extends orthogonal to the rigid surface portions 160, 144 if the bed platform panel 100 a for receiving the piston arm 605 of a tensioning device 610 (see, e.g., FIG. 6).

By one approach, a tensioning device 610 may take the form of a hydraulic piston such as a gas piston. In one embodiment, the tensioning device 610 is contained in and coupled to piston housing 600. The piston housing is mounted to one of the cross members 140 and provides a constant force biasing the bed platform panels 100 a towards the fully extended position. Thus, if not locked into position, the bed panel portions 105, 107 will fully extend to their longest most length of the panel 100 a. In one configuration, the tensioning device 610 comprises a piston arm 605 and a piston receiving barrel 607 such that the piston arm 605 is mounted to the tab 164 via, for example a bolt 515 that screws onto the end of the piston arm.

FIG. 7 illustrates one of the latches 700 corresponding to the latch receiver plates 146, 148, which can be used to secure the panel portions 105, 107 relative to one another such that they are prevented from extending relative to one another. The latch 700, by one approach, is secured to the cross member 152 via a bolt 710 and screw 705. As illustrated, the latch 700 has a hollow portion 720 that permits users to easily grasp and manipulate the latch 700 and a head portion 720 for inserting a projection of the head portion 720 into the latch receiving structures of the latch receiver plates 146, 148 discussed above and illustrated in FIG. 6. Tab 715 prevents the latch 700 from bending too far and breaking or becoming inoperable. The tab 715 is coupled or integral to the cross member 152.

FIG. 8 illustrates the head portion 725 of the latch 700 in a latched or secured position. More specifically, in the latch configuration, the latch 700 prevents the bed platform panel portions 105, 107 from moving relative to one another, i.e., extending or retracting the panel.

As mentioned above, the platform panels 100 may be secured relative to the interior cargo area of the vehicle 50 via coupling mechanism such as, for example, rails and tracks. FIG. 9 illustrates one exemplary bed rail 125 b, which is secured or attached to optional vertical tracks 150 c and 150 d disposed on an interior wall of a cargo area. While FIG. 9 illustrates the bedrail 125 b is associated with vertical tracks 150 c. 150 d, the bedrails 125 also may be secured directly to the interior wall of the cargo area of the vehicle in some configurations.

In one illustrative installed configuration, the bed rail 125 b is secured or mounted to the vertical rails 150 c, 150 d using two bolts 931, 932. By one approach, the bolts 931, 932 are adjacent a pair of tabs 921, 922. The tabs 921, 922 are, for example, integrally formed on or welded on the bed rail 125 b and may reinforce or otherwise help secure the bed rail 125 b. The bolts 931, 932 couple to screw posts 941, 942 extending from the vertical tracks 150 c, 150 d. FIG. 11 illustrates a close up view of a single such coupling between the vertical rail 150 c and the bed rail 125 b. FIG. 9 illustrates the tracks or rails 150 c, 150 d having a slot within which extension portions of the bed rails (e.g., the bolts 931, 932 and screw posts 941, 942) are configured to move to permit the bed rail 125 b to be adjusted along the height or length of the first and second pair of tracks. By one approach, the bedrail 125 b and tracks 150 c, 150 d may be formed of a variety of materials, such as, for example, metal, such as steel, or composite materials, among others.

FIG. 10 illustrates vertical track 1050 that corresponds to the vertical tracks 150 a, 150 b, 150 c, 150 d mentioned above. Further, screw post 1015 corresponds to the screw posts 941, 942. The screw post carriage 1010 extends perpendicular to the surface of the vertical track 1050 and sits in a screw post carriage 1010. Screw post carriage 1010 can travel freely within the vertical rail 1050 when a bed rail such as bed rail 125 b is not secured in place with a bolt. However, when the bolt is torqued down on the screw post 1015 the screw post carriage 1010 becomes locked into position within the vertical track 1050. The ability to easily move the screw post carriage 1010 up and down the vertical track 1050 makes it easy to adjust the height at which, for example, the bed platform panels 100 a are installed.

Returning the FIG. 9, the bed rail 125 b, like the bed rail 125 a, has both a frame receiving section 905 and a bed platform end portion coupling sections 910 running the length of the bed rail. The frame receiving sections 905 receiving the frame portions 154, 156, 134, 136 of the bed platform panel 100 a while the bed platform end portion coupling sections 910 extend into the end portions 158 and 142 of the bed platform panel 100 a.

FIG. 12 illustrates the end of the bed platform panel 100 a. The end portion 1210 has a duck-beak-like structure corresponding the contour 1310 of the bed rail 125 b as illustrated in FIG. 13. By one approach, the end portion 1210 with the corresponding duck-beak-like structure has a top wing or extension and a bottom wing or extension such that the end portion 1210 has a substantially c-like cross section, as illustrated in FIG. 15. More particularly, a cross section taken across line 15-15 of FIG. 1 illustrates the end portion 1210 mated with the contour 1310 of the bed rail 125 a in FIG. 15. The end portion 142, 158 both have the above described duck-beak-like structure shown in FIG. 15. The end portion 1210 takes attaches onto or secures to the bed rail 125 b due to their corresponding duck-beak-like structures and thus forms a superior couple to the bed rail 125 b as opposed to previous mounting structures. FIG. 14 illustrates a user mounting a bed platform panel such as bed platform panel 100 a to a bed rail such as bed rail 125 b. As the bed platform panel 100 a is slide into place and lowered into a horizontal position, the bed platform panel 100 a attaches onto the bed rail 125 b.
